At last the new house looks like it's starting to get somewhere.
It only took a few minutes work with the prong to scribe the stone cladding onto the wall around the garage door and then I was able to fix the bits of the north wing of number 22 into a box shape.
I've also taken the chance to fit a couple of internal spacers to make sure the walls don't get squeezed in the middle.
I also need to cut, and scribe the front wall of the garage. That is a very crucial part because it is the bit that connects this house to number 23 so it has to be made very accurately and the height of the buildings will have to line up exactly.
